=== Procedure to Bleed Brake System ===

First, apply the brake pedal several times with the engine off to remove the vacuum built up in the booster. The pedal should feel firm after a few presses.

Ensure the master cylinder is full of fluid and keep it at least half full throughout the process.

⚠️ Note: If the fluid drops too low at any point, air may enter the system. You must restart the process if this happens.

⚠️ Caution: Never mix fluid types or reuse old fluid — this can damage brake system components.

==== Step-by-Step Bleeding Order ====

Begin with the '''Left Rear wheel''', the farthest from the master cylinder. Then proceed in this order:

* Left Rear
* Right Rear
* Left Front
* Right Front

==== Bleeding Procedure ====

* Loosen the bleeder valve to break it free, then re-tighten slightly so it can be easily opened and closed.
* Place one end of a clear plastic hose on the bleeder valve and submerge the other end into a small container filled with fresh brake fluid.
-

Example: Bleeder valve setup with tubing and fluid container.

* Have an assistant pump the brakes several times to build pressure. On the final pump, they should hold the pedal down firmly.
* With the pedal held, open the bleeder valve slightly. Allow fluid and air bubbles to exit through the tube.
* When the fluid flow slows or the pedal reaches the floor, close the valve. Repeat until no air bubbles are seen in the fluid.
-
Tighten the bleeder valve to
'''6.5 ft-lbs'''. Move on to the next wheel and repeat the procedure.

✅ Check the master cylinder often to ensure the fluid level doesn’t drop.

Hope this helps with Bleeding your braking system of air.
